Anybody can aim a laser pointer to hit a target. But can you do it with an obstacle in your way? How about multiple obstacles? In this project, students will create and play a game in which the object is to maneuver a laser through a maze of obstacles to hit a target. To maneuver a laser, students will calculate the exact placement of multiple mirrors to reflect the beam of light through the game board. Challenges added throughout the game require students to understand and apply various geometric concepts.
What Inspired the Project?
Rod was inspired to do this project while working on the San Diego Bay Field Guide. His students were doing research along the bay and a student brought in a high intensity laser to help with taking measurements across a boat channel. He’s been wanting to use these lasers for a project ever since. Recently a student made a comment that he made his students reflect more than mirrors which sparked the idea for the project. Rod understands that not everybody has access to high powered lasers. So he wanted to create a project using a regular laser pointer. Part of what makes PBL so successful is that it provides cool ways for students to engage in the subject. And what could be cooler than lasers?
